Title: Detection circuit for narrow pulse width
Inventor: SHIBUYA MANABU
IPC: G01R29/02
Filed: 1989-12-28
Abstract: PURPOSE:To prevent a malfunction caused by the pulse having reverse polarity of extremely narrow width and to accurately decide a comparison time by using a delay line which is hardly affected by environments. CONSTITUTION:By a variable delay element 20 capable of setting a delay time (comparison time) from outside data, the input signal is delayed for a specified time and outputted. The signal becoming LOW level at the rise edge of input signal and HIGH level at the fall is generated by an edge detecting part 21, and when the input signal falls down from the rise within the comparison time, the HIGH level state is kept during the input signal rises after the finish of comparison time. The state of edge detecting signal at the time after the comparison time is elapsed from the rise edge of input signal is latched by a narrow pulse detecting part 22. Since the edge detecting signal is in the HIGH state when the pulse having the width narrower than the comparison time exists, the output OUT is also in the HIGH state.

Title: Evaluation method for crystal defect
Inventor: SUGIHARA KOHEI
IPC: G01N23/20
Filed: 1997-12-16
Abstract: PROBLEM TO BE SOLVED: To obtain an evaluation method in which the existence, the kind, the density and the distribution in the depth direction of a crystal defect can be measured simultaneously, quickly and nondestructively by judging the energy positions of luminescent light analyzed for every wavelength and the peak intensities and discriminating the sizes of the peak half widths with respect to specified values. SOLUTION: A semiconductor 11 is irradiated with a laser beam 13, and luminescent light 17 is radiated to the outside from the semiconductor 11. Then, the luminescent light 17 is narrowed down by a convex lens 18. Light which is narrowed down by the convex lens 18 and which is spectrally diffracted by a spectral device 19 is synchronized with a signal from a chopper 14 inside a lock-in amplifier 20 so as to be discriminated from a noise. The signal is converted into digital data by an A/D converter 21 so as to be analyzed and processed by a computer system 22. At this time, when the energy position of an emission peak due to a crystal defect is investigated, the kind of the crystal defect can be analyzed. In addition, since the intensity of the emission peak is proportional to the density of the crystal defect, the density can be analyzed at the same time.  In addition, whether the half width of the emission peak is larger or smaller than 0.1 V is judged. Thereby, the kinds of the crystal defects can be discriminated more precisely.
